Thermally-conductive gap fillers are described. The gap fillers comprise an aziridino-functional polyether polymer and thermally conductive particles. Initiators suitable for such systems ae also described. Such gap fillers may be used in various applications including the manufacture of battery modules and subunits.

Aziridino-functional polyether thermally-conductive gap filler

The invention relates a process for producing isocyanates comprising the steps of a) providing an azolide and optionally a solvent, and b) adding an acid at a temperature below about 40 C. The invention also relates to the isocyanate obtainable by such a process.

Process for producing isocyanates

The invention relates to a radiation curable composition for taking a dental impression comprising (A) a cationically hardenable compound comprising at least one aziridine moiety, and (B) a radiation sensitive starter, the radiation sensitive starter comprising an onium salt, a ferrocenium salt, a combination or mixture thereof.

Radiation curable composition, process of production and use thereof

The invention relates to a dental composition comprising a) a compound (A) with the following features: only one backbone unit (U) with 6 to 20 carbon atoms, at least 6 carbon atoms thereof forming an aromatic or an aliphatic cyclic moiety, the remaining carbon atoms either being part of substituents pending from the cyclic moiety or being part of bridging groups to spacer units, wherein one or more of the remaining carbon atoms can be replaced by an oxygen atom, the backbone unit not comprising a bisphenol structure and halogen atoms, one or two unit(s) (S) being connected to the backbone unit (U) via an ether linkage, at least one unit (S) comprising a &#x2014;CH2-CH2-CH2-CH2-O&#x2014;CH2-CH(Q)-OG moiety or a &#x2014;CH2-CH(OG)-CH2-OM moiety or a mixture of these two types of moieties within one unit (S), with G comprising at least one polymerizable moiety and an urethane moiety, the urethane moiety acting as connecting element to unit(s) (S), and M comprising at least one group selected from acroyl, methacroyl, aryl, mixtures and combinations thereof, Q comprising at least one group selected from hydrogen, methyl, phenyl, phenoxymethyl, mixtures and combinations thereof, and with the proviso that onto the backbone unit (U) at least two substituents are attached, each bearing at least one group G, wherein in the case where only one unit (S) is present, the group G not being part of said unit (S) is located in the further substituent pending from unit (U), b) a filler (B) and c) an initiator (C).

Dental composition, kit of parts and use thereof

The invention relates to and their preparation and the production of Silicon-Isocyanates from Silicon-Urea-Azolides.

Silicon-urea-azolides, their preparation and use in the preparation of silicones with isocyanate terminal groups

The invention relates to curable silicone compositions which contain silane based crosslinkers and a mixture of different organopolysiloxanes. The compositions are particularly suitable as curable impression materials in dental applications.

Curable silicone impression materials with high tear strength and low consistency

The present invention relates to a multicomponent automixable putty impression material, its components, mixtures of the components and a method for obtaining impressions with the multicomponent automixable putty impression material.

Automixable putty impression material

The invention provides a method to reduce evolution of hydrogen gas especially during pouring gypsum models from addition cured silicones. In this respect the invention relates to an addition curable silicone composition, comprising an addition-curable siloxane compound, a siloxane crosslinker, a catalyst and an unsaturated silane compound with at least one methylene group directly attached to the unsaturation in an amount effective to reduce the amount of hydrogen gas evolved in the reaction of said composition.
